2 Claims. (Cl. 118259) This invention relates to adhesive or glueapplying means and this application is a division of application SerialNo. 482,931, filed January 20, 1955.

The mechanism has been developed for applying adhesive to a strip ofpaper and has for its salient object to provide glue or adhesiveapplying mechanism so constructed that the glue applying wheel will notwear and will not stick, after use.

Further objects of the invention will appear from the followingspecification taken in connection with the drawings which form a part ofthis application, and in which Fig. l is a side elevation of mechanismconstructed in accordance with the invention;

Fig. 2 is a top plan view of the structure shown in Fig. 1;

Fig. 3 is a sectional elevation taken substantially on line 3-3 of Fig.2, looking in the direction of the arrows; and

Fig. 4 is a sectional elevation taken substantially on line 44 of Fig.3, looking in the direction of the arrows.

In the particular embodiment of the invention illustrated, there isshown a table or plate 30 supported by suitable frame members and overwhich a strip 33 is led from a suitable supply roll around rollers 34and 35 and downwardly beneath a roller 36 to the top of the table 30.

After the strip 33 leaves the guide roller 36, it is drawn beneath aglue roller or wheel 45 by suitable strip feeding mechanism. The wheelor roller 45 is mounted on a spindle 46 which has a sprocket wheel 47secured thereto. The sprocket wheel 47 is driven by a chain 48 from asuitable source of power.

The spindle 46 is mounted on an arm 49 which is mounted on a fixed pivot50 and has at its opposite end a vertical sleeve 51 which receives athreaded stud 52 which is secured to and extends upwardly from the sideframe member 31. A spring 53 is mounted on the stud 52 and a nut 54 atthe upper end of the stud exerts through the spring a resilient downwardpressure on the arm 49 and on the shaft 46 and glue wheel 45 carriedthereby.

The spindle 50 which is carried by a suitable bracket 55 has pivotallymounted thereon a glue pot 56. It will be noted that the glue wheel 45rotates between a pair of blocks 57 and 58 which are formed from asuitable 2,862,471 Patented Dec. 2, 1958 "ice non-abrasive yet hard,rigid, synthetic plastic material. Certain thermosetting phenolicresinous materials, sold under the name Bakelite, a trademark of theBakelite Company, can be used for this purpose. It will also be notedthat the lower end of the glue pot is cut away, as shown at 59, toreceive the wheel 45. vThe blocks 57 and 58 act as wipers and because ofthe nature of the material of which they are made will not cause anywear on the glue wheel 45, which may be made of brass or other suitablematerial. Furthermore, there will not be a tendency for the wheel tostick between the blocks.

A pivoted wiper 60 rests against the rim of the Wheel 45 and removesexcess glue therefrom. It will be noted from the showing in Figs. 4 and5 that a screw 61 is mounted in a lug 62 on the glue pot and bearsagainst the upper edge of the arm 49. By turning this screw the glue potcan be tilted about the spindle 50, thus varying the amount of contactbetween the glue in the pot and the rim of the wheel. In this way theamount of glue carried by the wheel to the strip can be regulated.

From the foregoing description it will be evident that because of thenature of the material of the blocks 57 and 58, these blocks will notcause the side faces of the wheel 45 to wear and, moreover, the wheelwill not stick to the blocks.

Although one specific embodiment of the invention has been particularlyshown and described, it will be understood that the invention is capableof modification and that changes in the construction and in thearrangement of the various cooperating parts may be made withoutdeparting from the spirit or scope of the invention, as expressed in thefollowing claims.

What we claim is:

1. Glue applying means comprising a glue pot having an open end, a gluewheel rotatable through said opening, and blocks on said glue pot at theopen end thereof, said blocks constituting walls for the said potadjacent the glue wheel, and said blocks being spaced apart to closelyfit against the side surfaces of the wheel and receive the wheeltherebetween, said blocks being formed of hard, rigid, non-abrasiveplastic material.

2. Glue applying means comprising a pivoted glue pot having an open end,a glue wheel rotatable through said opening, blocks on said glue pot atthe open end thereof, said blocks constituting walls for the said potadjacent the glue wheel, and said blocks being spaced apart to closelyfit against the side surfaces of the wheel and receive the wheeltherebetween said blocks being formed of hard, rigid, non-abrasiveplastic material, and means for adjusting said glue pot on its pivot.
